To solve the problem regarding the Wheatstone bridge and the effect of interchanging resistances in arms Q and S, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Wheatstone Bridge**: In a Wheatstone bridge, we have four resistances arranged in a diamond shape. Let’s denote the resistances as follows: - Arm P: Resistance \( R_P \) - Arm Q: Resistance \( R_Q \) ...
